Skip season 1 & 2 and go right to season 3. The captains made watching this very enjoyable, unlike the previous seasons which were a lot 'colder'. Jackson, Yibo, Yixing, and Wallace all showed great respect to the dancers which the dancers also return to them. And the dancers themselves show great sportsmanship. No dirty editing (or at least none that I could make out). Heck, even the commercials are fun to watch.
The moments I always go back to include the captains' battles and cypher in episodes 1&2, Tao & Cici's emotional couple dance, the whole water stage episode, and Chun Li's first battle.
The only disappointing part for me is the bias towards certain teams/people. There were certainly many performances that I thought should have won over others (coming from a dancer's perspective myself).

Overall, this show is good for both people with or without dance knowledge.

Edit: I've returned from watching a few episodes of HBDC and I must say that SDC is way better.
